Filed: 1998-08-14
Granted: 2005-01-11
Abstract: A method of preventing destructive ice rupture impulsive forces on an overhead electric line from reaching and damaging the transmission line towers. The invention comprises forming short barrier segments of greatly reduced ice thickness at points on the conductors and static wires in the line spans on each side of the towers to be so protected. The short barrier segments so formed have a reduced tensile strength of ice proportional to their reduced ice cross-sectional area; they then fracture at a proportionately lower rupture force and thereafter the rupture discontinuity so formed presents a barrier to the transmission of any large destructive rupture forces to the towers from ice rupture on any unprotected portion of the line. The protective short segments of reduced ice thickness are formed by melting the ice thermally or chemically, or alternatively by attaching a short shield or cover over and around the conductor or static wire at the desired points so as to prevent the accretion of supercooled freezing rain, drizzle, fog, cloud or wet snow on the short segments of the conductors or static wires protected by the shields.
